the b50 is 50% bio mixed with diesel and b5 is 5% bio and so on

 

You don't need to change anything.

 

Being on the repair end of things..... and remembering some of the issues that bio/wvo brought about back in 08 when the price went to the moon, I won't be running anything but what comes out of the approved pump for some time.

 

When you toss out stuff like that, you ought to give a little information to support it. Exactly what problems are you referring to with the wvo and biodiesel, other than clogging filters and degrading rubber fuel lines? C'mon, help us out a little. There is a lot of interest in this stuff. If you know of damage or other problems caused by this stuff, give us the scoop!

 

I know this thread is dead, but I plan on making some biodiesel when I get home and my primary base of information is coming from Journey to Forever.
Would you guys mind elaborating on what exactly is mis-information on their site? Is it in the production process?
Also, do you have a source for the polymerization in the common rail? You're the first and only person I've heard mention that and don't want to go to all the trouble only to find out it jacks up my fuel system, aside from dislodging crud in the tank and lines.

Thanks in advance!

 

I ran about 80 gal of B20 in My truck and it cleaned the he!! out of my fuel system. I need to find some 50 gal drums to start making my own Bio. I have about 60 gal of used vegi oil in the shop and need to find a way to use it. I met a guy at work that mixes 50% used vegi Oil and 50% Diesel in his Duramax and has not had a problum???????

 

So does this guy process the WVO into biodiesel or does he just filter the fry chunks out and mix it directly with petro-diesel?

 

Polymerization is the oxidation of biodiesel. As it ages (oxidize) it turns into a hard varnish like substance. There's been reports that under extreme pressure this is accelerated. Biodiesel does have a shelf life so rule of thumb is to the use the freshest available.

I found a descent article about Biodiesel. Pretty good explanation of the Polymerization among many other things. Some of it's pretty geeky (ie. over my head) but I found some good info.

 

At the University I work at I've learned alot about bio fuels. There are goods and bads with it as with all fuels. Purity is the main issue with bio diesel this is were issues start. I also learned this week that up to 5% of tank of Reg diesel contains biodiesel as a filler and additive. Also it's cheaper to produce but they don't modify the price to reflect that. Just a interesting tid bit I learned and wanted to share.

 

I'm happy to see so many people making biodiesel. I've been making it for 5 years, have a 40 gallon plant and several 100 gallons of used cooking oil. I get my oil on offshore rigs and some is better than others. It's not as easy as some of you make out if you try to make it near perfect. I read all I could get my hands on before I heated up the first oil for titration.Removal of the DI & triglycerides it important. At high temps they will turn into polymer and scratch your liner or cylinder wall (quote from biodiesel.org). I sent a gallon of my first batch to MSU lab and it came back with a little too much methanol but was okay to use a small percentages. I still make and use it in my tractors, generator & 2000 5.9 but not in my 6.7 gets only 15 ppm. I like the lubricity that comes from biodiesel, your engine will run quieter especially older engines. When they took the sulfer out of diesel it took out the lubricity out. If I'm traveling I add a 200 to 1 ratio of 2 cycle motor oil in my older truck to lub the pumps & injectors.

 

I know that people have different opinios of this stuff... But I have been running straight bio-diesel from a small company here local at the cost of $3.19/gal for the last year. No issues. I mean NONE. My truck runs the same with or without it. It just smells like veggie oil instead. The small plant has there Bio checked all the time by the feds and what-not. I know this cuz I look at the results about every other time. It is certified B99. The owners always ask me if I have been running regular diesel or not, and when I changed my fuel filter out just to make sure. I forgot one time to change the filter and it clogged up on me. I popped the old one out and a new one in, and my trouble code reset within 20 miles. I dont count that as an issue cuz it was my own fault not changing the filter out. In the cold winter, I do run about half and half.... otherwise- I run it straight- with Zero changes to my truck for the biodiesel.
